1 tablespoon cornstarch mixed with 2 tablespoons cold water (slurry)
Instructions
In a bowl, toss the cut chicken pieces with salt, pepper, and 1/2 cup cornstarch until lightly coated.
Heat the vegetable oil in a large skillet or wok over medium-high heat. Add the coated chicken in a single layer (work in batches if necessary) and cook until golden brown and cooked through, about 5-7 minutes. Remove the chicken and set aside.
While the chicken cooks, prepare the sauce. In a small saucepan, combine orange juice, sugar, soy sauce, rice vinegar, ginger, garlic, and sesame oil. Bring the mixture to a simmer over medium heat, stirring until the sugar dissolves.
Whisk the cornstarch slurry into the simmering sauce. Continue to cook, stirring constantly, until the sauce thickens significantly and becomes sticky, about 1-2 minutes.
Return the cooked chicken to the skillet. Toss gently until every piece is fully coated in the sticky orange glaze.
